Overview

CMMG's 55CA6C5 kit contains the parts needed to finish a stripped AR-15 lower. It includes the fire control group, trigger guard, A2 pistol grip, takedown and pivot pins, bolt catch, magazine catch, safety selector, buffer retainer, and their springs and detents.

The color-coded packets keep the small pieces organized during assembly. The included trigger and grip make the kit a complete starting point, while the builder still lets you replace either one with an upgrade.

  • A2 pistol grip with screw and washer
  • Trigger guard with roll pin
  • Takedown and pivot pins with detents and springs
